Unitarity and Entropy: From Black Holes to Baryons

This lecture explores the connection between unitarity and entropy, starting from black holes and extending to baryons. It delves into the saturation of entropy bounds, the behavior of various quantum field theory objects at the saturation point, and the concept of 'saturons'. The presentation discusses the universal bounds imposed by unitarity on QFT objects, the implications of these bounds on scattering amplitudes, and the similarities between black holes and saturons. The instructor also covers the microscopic theory of black holes, the decoding of quantum information stored in baryons through pion scattering, and the evidence supporting the idea of a black hole N-portrait.
